<p>GStreamer elements can throw non-fatal warnings and fatal errors.
Higher-level elements and applications can programmatically filter
the ones they are interested in or can recover from,
and have a default handler handle the rest of them.</p>
<p>The rest of this section will use the term <span class="quote">“<span class="quote">error</span>”</span>
to mean both (non-fatal) warnings and (fatal) errors; they are treated
similarly.</p>
<p>Errors from elements are the combination of a <a href="/usr/share/gtk-doc/html/glib/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> and a debug string.
The <a href="/usr/share/gtk-doc/html/glib/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> contains:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>a domain type: CORE, LIBRARY, RESOURCE or STREAM</p></li>
<li class="listitem"><p>a code: an enum value specific to the domain</p></li>
<li class="listitem"><p>a translated, human-readable message</p></li>
<li class="listitem"><p>a non-translated additional debug string, which also contains</p></li>
<li class="listitem"><p>file and line information</p></li>
</ul></div>
<p>Elements do not have the context required to decide what to do with
errors.  As such, they should only inform about errors, and stop their
processing.  In short, an element doesn't know what it is being used for.</p>
<p>It is the application or compound element using the given element that
has more context about the use of the element. Errors can be received by
listening to the <a class="link" href="GstBus.html" title="GstBus"><span class="type">GstBus</span></a> of the element/pipeline for <a class="link" href="GstMessage.html" title="GstMessage"><span class="type">GstMessage</span></a> objects with
the type <a class="link" href="GstMessage.html#GST-MESSAGE-ERROR:CAPS"><code class="literal">GST_MESSAGE_ERROR</code></a> or <a class="link" href="GstMessage.html#GST-MESSAGE-WARNING:CAPS"><code class="literal">GST_MESSAGE_WARNING</code></a>. The thrown errors should
be inspected, and filtered if appropriate.</p>
<p>An application is expected to, by default, present the user with a
dialog box (or an equivalent) showing the error message.  The dialog
should also allow a way to get at the additional debug information,
so the user can provide bug reporting information.</p>
<p>A compound element is expected to forward errors by default higher up
the hierarchy; this is done by default in the same way as for other types
of <a class="link" href="GstMessage.html" title="GstMessage"><span class="type">GstMessage</span></a>.</p>
<p>When applications or compound elements trigger errors that they can
recover from, they can filter out these errors and take appropriate action.
For example, an application that gets an error from xvimagesink
that indicates all XVideo ports are taken, the application can attempt
to use another sink instead.</p>
<p>Elements throw errors using the <a class="link" href="GstElement.html#GST-ELEMENT-ERROR:CAPS" title="GST_ELEMENT_ERROR()"><span class="type">GST_ELEMENT_ERROR</span></a> convenience macro:</p>

<p>Things to keep in mind:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Don't go off inventing new error codes.  The ones
currently provided should be enough.  If you find your type of error
does not fit the current codes, you should use FAILED.</p></li>
<li class="listitem"><p>Don't provide a message if the default one suffices.
this keeps messages more uniform.  Use (<a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>) - not forgetting the
parentheses.</p></li>
<li class="listitem"><p>If you do supply a custom message, it should be
marked for translation.  The message should start with a capital
and end with a period.  The message should describe the error in short,
in a human-readable form, and without any complex technical terms.
A user interface will present this message as the first thing a user
sees.  Details, technical info, ... should go in the debug string.</p></li>
<li class="listitem"><p>The debug string can be as you like.  Again, use (<a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>)
if there's nothing to add - file and line number will still be
passed.  <a class="link" href="gstreamer-GstGError.html#GST-ERROR-SYSTEM:CAPS" title="GST_ERROR_SYSTEM"><span class="type">GST_ERROR_SYSTEM</span></a> can be used as a shortcut to give
debug information on a system call error.</p></li>
